RELAY ON-VEHICLE INSPECTION

PROCEDURE

1. INSPECT NO. 1 INTEGRATION RELAY (FUEL PMP)

   
   

   1. Remove the No. 1 integration relay Click here.

   2. Measure the resistance of the FUEL PMP fuse.

      
      

      1. Measure the resistance according to the value(s) in the table below.

         Standard Resistance
         Tester Connection Condition Specified Condition FUEL PMP fuse Always Below 1 Ω

         If the result is not as specified, replace the FUEL PMP fuse.

   3. Measure the resistance of the FUEL PMP relay.

      Measure the resistance of the IG2 relay.

      
      

      1. Measure the resistance according to the value(s) in the table below.

         Standard Resistance
         Tester Connection Condition Specified Condition 1C-1 - 1B-8 Battery voltage not applied to terminals 1B-6 and 1B-7 10 kΩ or higher 1C-1 - 1B-8 Battery voltage applied to terminals 1B-6 and 1B-7 Below 1 Ω

         If the result is not as specified, replace the No. 1 integration relay.

   4. Install the No. 1 integration relay Click here.

3. INSPECT EFI MAIN RELAY (EFI MAIN)

   

   
   

   1. Measure the resistance according to the value(s) in the table below.

      Standard Resistance
      Tester Connection Condition Specified Condition 3 - 5 Battery voltage not applied to terminals 1 and 2 10 kΩ or higher 3 - 5 Battery voltage applied to terminals 1 and 2 Below 1 Ω

      If the result is not as specified, replace the EFI MAIN relay.

4. INSPECT FUEL FILTER RELAY (FUEL FILTER)

   

   
   

   1. Measure the resistance according to the value(s) in the table below.

      Standard Resistance
      Tester Connection Condition Specified Condition 3 - 5 Battery voltage not applied to terminals 1 and 2 10 kΩ or higher 3 - 5 Battery voltage applied to terminals 1 and 2 Below 1 Ω

      If the result is not as specified, replace the FUEL FILTER relay.
